Abstract: An indication of a set of premises between which network traffic is to be routed via a private fiber backbone of a provider network is obtained. Respective virtual routers are configured for a first premise and a second premise, and connectivity is established between the virtual routers and routing information sources at the premises. Contents of at least one network packet originating at the first premise are transmitted to the second premise via the private fiber backbone using routing information obtained at the virtual routers from the routing information source at the second premise.

Abstract: Techniques are described that enable users to configure the mirroring of network traffic sent to or received by computing resources associated with a virtual network of computing resources at a service provider network. The mirrored network traffic can be used for many different purposes including, for example, network traffic content inspection, forensic and threat analysis, network troubleshooting, data loss prevention, and the like. Users can configure such network traffic mirroring without the need to manually install and manage network capture agents or other such processes on each computing resource for which network traffic mirroring is desired. Users can cause mirrored network traffic to be stored at a storage service in the form of packet capture (or “pcap”) files, which can be used by any number of available out-of-band security and monitoring appliances including other user-specific monitoring tools and/or other services of the service provider network.

Abstract: Technologies are disclosed for monitoring network traffic using traffic mirroring. According to some examples, traffic mirroring allows customers to monitor traffic at different sources within a VPC. For example, a source may be any Elastic Network Interface (ENI) in their VPC, including elastic network interfaces (ENIs) on virtual machine instances, Network Address Translation (NAT) Gateways, Load Balancers, VPC endpoints, Internal Gateways, Transit Gateways, and more. Filters can be utilized to determine the network traffic to mirror. A customer may also configure to monitor real-time traffic with a monitoring appliance of their choice. With traffic mirroring, data traffic may be identified and sent to one or more target devices. Customers may monitor traffic within a VPC for content inspection, forensic analysis, troubleshooting, record keeping, and the like.

Abstract: A message indicating an auxiliary task associated with traffic transmitted via a virtual router between a pair of isolated networks is received at an offloading device. A stack multiplexer at the offloading device selects a protocol stack instance to process the message. A result of the auxiliary task is obtained by the multiplexer from the selected protocol stack instance and transmitted to the virtual router, where it is used to transmit a packet between the isolated networks.

Abstract: A pair of virtual routers is configured. In response to programmatic requests, dynamic transfer of routing information between the routers in accordance with configuration settings indicated by a client is enabled. The routing information is associated with a set of isolated networks to which the virtual routers are attached. A network packet originating at an address in a first isolated network is transmitted to an address in a second isolated network using a route determined from routing information transmitted between the virtual routers according to the configuration settings.

Abstract: Techniques for networking in provider network substrate extensions are described. A compute instance of an isolated virtual network is hosted by an extension of a provider network that is in communication with the provider network via a secure tunnel through a customer network. A request to establish communications between the isolated virtual network and the customer network is received at an interface to the provider network. A message to cause a gateway of the extension to route traffic between the isolated virtual network and the customer network is sent via the secure tunnel.

Abstract: Managed multicast communications may be implemented across isolated networks. A virtual traffic hub may be implemented that connects different isolated networks. A control plane for the virtual traffic hub may accept requests to enable a multicast group between different isolated networks connected to the virtual traffic hub. The multicast group may then be enabled at the virtual traffic hub so that requests to add members to the multicast group and data packets directed to the multicast group can be handled according to multicast protocols by the virtual traffic hub.

Abstract: Disclosed are various embodiments of a stateful network router. In one embodiment, a stateful network router intercepts a network data connection between a first host and a second host on a network. The stateful network router routes first data packets from the network data connection sent by the first host to the second host to a target. The stateful network router also routes second data packets from the network data connection sent by the second host to the first host to the target.

Abstract: A method and apparatus of a network element that dynamically establishes a first virtual private network (VPN) tunnel is described. In an exemplary embodiment, the network element detects data destined for a first private subnet. In response to the detecting, the network element determines that a next hop for the data does not have an established VPN tunnel that allows access to the first private subnet. The network element further establishes the VPN tunnel and sends the data using the VPN tunnel.

Abstract: A method for license management. The method includes receiving a first license request for a feature from a network element and in response to the first license request, making a first determination that no feature licenses of a first type are available for the feature. The method further includes based on the first determination, making a second determination that a feature license of a second type is available for the feature, and providing the feature license of the second type to the network element.
